Constantius Gallus

Constantius Gallus was a member of the Constantinian dynasty appointed Caesar in the eastern Roman Empire. His government at Antioch became associated with repression and conflict with imperial officials, and Constantius II eventually recalled and executed him.

In Gore Vidal’s Julian, their correspondence frames Julian’s own account of survival within Constantine’s dynasty: the massacre of his relatives, his education under Christian supervision, the execution of his half-brother Constantius Gallus and his dangerous service under Constantius II.
